I was wondering if anyone knows of a good place around Western NC to have headwork done on an inline. I was thinking of having them ported and polished because I know this is one of the weaker links in the inline and I still haven't done it. What kind of gains would I be looking at by doing this. I have a 270 Clifford cam, Clifford intake and a Weber 38. Last I would like to know what is a reasonable price to have decent work done.
